37. ἀσκούς. ‘Wine-skins.’ Our Lord often illustrates two aspects of the same truth by a pair of parables (e.g. the Hid Treasure and the Pearl; the Sower and the Tares, &c.). The skins used for holding wine were apt to get seamed and cracked, and old wine-skins would tend to set up the process of fermentation. They could contain the motionless, but they could not expand with the fermenting. To explain this passage, see Excursus III.
